Light Weight Snl7 3p Series ( MCB ) Miniature Circuit Breaker 63A 10ka

Hot Sale Snl7 3p Series (MCB) Miniature Circuit Breaker 63A 10ka​

GENERAL

SNL7 series high breaking capacity mini circuit breaker is used in AC50/60Hz, rated voltage of 230V

3, 4 poles 400V, rated current to 63A for overload and short-circuit protection as well as for unfrequented switching under normal case.It is used extensively for industry, commercial and household.This product conform to IEC60898 standard.

1.Application:For protecting cables and equipments against overload and short circuit.

2.General rules for choosing MCB.

a.Technical data of the network at the point considered

The earthing systems,short-circuit current at the circuit breaker installation point,which must always be less than the breaking capacity of this device,network normal voltage.

b.There are 3 curvve characteristics for magnetic operation:

B curve (3-5In) protection and control of the circuits against length cables in TN and IT systems.

C curve (5-10In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.

D curve (10-14In) protection and control of the circuits against overloads and short-circuits; protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers,breakdown lamps.)

Advantages:

High breaking capacity , all rated current can reach 6KA;

Many kinds of accessories can be chosen, in modularize and flexibility combine that make the customer install conveniently;

The cover and function parts both are made of inflaming retarding, bear high temperature and bear impact plastic;

The breaker is applicable to lighting distribution system in industrial enterprise, commercially district, high-rise building and dwelling house.
